Senior🎓
Top SchoolXing Du is a Senior Staff Software Engineer in San Francisco with 11 years of hands-on experience building high-performance, cost-efficient backend systems across gaming, consumer, and fintech companies. He blends a background in computer security, networking, and game tech with full-stack expertise, favoring “you build it, you run it” ownership to push scalability and reliability to the limits. A fast learner who seeks challenges outside his comfort zone, he’s driven by performance tuning and operational excellence rather than feature gloss. His career includes leadership roles at Zynga, Snap, Opendoor, and now Affirm, where he focuses on designing infrastructure that balances latency, throughput, and cost. Notably, his trajectory from cryptography research and game R&D to production infrastructure gives him a rare combination of low-level security insight and large-scale systems experience.
